[11u] RFR(M): 8233787 backport: Break cycle in vm_version* includes

[Schmidt, Lutz]

Dear Community, 

I would appreciate receiving reviews for this downport change. It consists of many modified files. In most cases, it’s only #include statement changes, caused by factoring out abstract_vm_version.{c|h}pp from vm_version.{c|h}pp. The change did not apply cleanly, for the most part because of this split. The other merge conflicts were trivial (include rearrangement and copyright headers).

Tests:
SAP's internal build and test farm (all OpenJDK platforms (no 32-bit), and more). Tests include JCK, jtreg (hotspot and jdk), and SAP-private tests. No issues found.

Your effort is very much appreciated!

Thanks,
Lutz

P.S.: build-dev on CC: because a small build change is included.
